I didn't notice it was the same cab...If it was, then Flo was definitely wrong. Although, I can see that maybe she thought T&I were done with it. Still, the yelling wasn't really necessary - although I might do a bit of voice-raising myself in that stressful situation in a foreign country.

I don't think Flo was aware that it was Ian and Teri's cab, that's how I read the situation.
I saw it as an honest mistake on her part which Ian, as usual, had to make into an opportunity to show what an ass he can be.

I was just rewatching, to start my recap and Flo saw the cab, walked over, had a discussion, and the cabbie AGREED to take them to the train station. THEN ian jumped all over everyones a$$ and demanded the Taxi stay.

Flo and Zach are the only team remaining of the pact of 4 that A&A has assembled to "get the twins". They've all been knocked off in the last 3 consecutive weeks, Heather and Eve, Mike and Kathy, and now Adriane and Aaron. Makes me think that if 9-1-1 can catch up with the pack that it might be Flo and Zach's turn to take the walk of shame next week.

I think it was the cab that I/T had used to get to the mosque, but Ian certainly did not need to be as rude and obnoxious as he was to Flo (Wait...what's this? I'm defending Flo? Where is my medication?). Flo said she didn't know it was T/I's cab, and that's certainly possible. There was no need for Ian to once again reinforce the "Ugly American" image that he has been so effectively demonstrating throughout the entire race so far...:nono
